an eyewitness to the 10/24/82 River Theater (Guerneville, CA) show, which we know featured the return of female vocalists after the brief four-show interregnum of 10/13 and 10/21-23, thought that "Julie" was one of the singers. This was how Julie Stafford first came to my attention as someone who might have sung onstage with JGB ...
I then noted in comments the following:
The eyewitness to the River Theater (Guerneville, 10/24/82) show is Julie A., and she is exceptionally credible. She and John saw a great fraction of Bay Area Jerry shows from '79-90s or so, and taped many of them. She may come post here, but in any case she says she is 100% sure that the backup singers on 10/24/82 were two white women, Julie and Liz ... And if Jaclyn and DeeDee didn't start on 10/24/82, then we have their debut date wrong, too.I believe I have this little conundrum solved: JGB also played the River Theater, Guerneville, CA, on May 31, 1982, and I believe that this is the Guerneville show with Liz and Julie singing. It would have been in the "Liz and Julie" period. Julie Anzaldo avers that the "Liz and Julie" show could have been 5/31. She remembers Roadrunner being played, but it was played at both Guerneville shows. There weren't any other particular rarities that might have set the two shows apart in memory, except perhaps for the guest shot by Matt Kelly on harmonica at the May 31 show (for "Mystery Train").
This may help to resolve two things in particular that had confused me. First, it restores the longstanding understanding that Jaclyn LaBranch and DeeDee Dickerson debuted on 10/24/82. Second, it reconciles with the Liz Stires chronology, which has her leaving after the 6/22/82 Mosque Show in Richmond, VA.
Update: I have posted listening notes on 5/31/82.
On the theater, I would love to learn more! Seems like my kind of place
